Abstract

The invention discloses a manual hydraulic lifting device in machining. A hydraulic pump is arranged above an oil tank and is connected to the oil tank, wherein a large hydraulic cylinder and a small hydraulic cylinder are arranged above the hydraulic pump; the small hydraulic cylinder is connected to the hydraulic pump; an opening is formed in the top of each of the large hydraulic cylinder and the small hydraulic cylinder; a positioning block is arranged between the large hydraulic cylinder and the small hydraulic cylinder and is fixed to the large hydraulic cylinder and the small hydraulic cylinder; a large piston is arranged in the large hydraulic cylinder; a support table is fixed on the top of the large piston and is arranged above the large hydraulic cylinder; a small piston is arranged in the small hydraulic cylinder; a pressing rod is arranged above the positioning block; the pressing rod is connected to a connector; the connector is fixed to the positioning block; a connection rod is arranged under the pressing rod and is respectively connected to the pressing rod and the small piston. The manual hydraulic lifting device is simple in structure, simple in principle, small in occupied area, low in cost and convenient to carry; metal parts can be lifted by using the principles of levers and hydraulic pressure; the manual hydraulic lifting device can be conveniently operated by operators.

Description

technical field [0001] The invention relates to a device, in particular to a manual hydraulic lifting device in machining. Background technique [0002] Petroleum, also known as crude oil, is a viscous, dark brown liquid. There are oil reserves in parts of the upper crust. The main component is a mixture of various alkanes, naphthenes and aromatic hydrocarbons. It is formed by the long-term evolution of organisms in ancient oceans or lakes, and it belongs to fossil fuels. Petroleum is mainly used as fuel oil and gasoline, and is also a raw material for many chemical industry products such as solutions, fertilizers, pesticides and plastics. The nature of petroleum varies with the place of origin, the density is 0.8-1.0g / cm3, the viscosity range is very wide, the freezing point varies greatly (30-60 degrees Celsius), the boiling point ranges from room temperature to above 500 degrees Celsius, and is soluble in various organic solvents. Insoluble in water, but can form emul...
